BMW R 850 / 1100 / 1150 GS & Adventure The high-quality closure is made of aluminum (natural) and was elaborately CNC milled/turned. This cover replaces the black, not particularly attractive plastic oil cap on your motorcycle. Fits all 4V boxer models that are closed with a bayonet. (A self-adhesive manufacturer emblem with a diameter of 21mm also fits into the recess. This is not included) “Keys” specially made for these parts that make opening easier and can easily be stored in the on-board tool kit. The quality of the product is of course “Made in Germany”.
